Sodium levels in salt. The American Heart Association (AHA) recommends that healthy adults reduce their sodium intake to no more than 2,400 milligrams per day. This is about 1 and 1/4 teaspoon of sodium chloride (salt).

They further recommend that if you have heart failure, you reduce your sodium to 2000 mg. Some doctors advise PAH patients to follow the AHA guidelines. Listings of the sodium content of various foods and other guidelines can be found on the AHA’s website (www.americanheart.org).
